Honeywell TDC 2000

The Honeywell TDC 2000 is a distributed control system (DCS) that made its debut in 1975 as one of the first commercially available DCS systems. It has found applications in diverse industrial processes, including oil and gas, petrochemical, refining, power generation, and manufacturing.

The TDC 2000 is a modular system with scalability to accommodate various applications. It comprises several key components:

  1. Controllers: Serving as the core of the TDC 2000 system, controllers execute control logic and facilitate communication with other system components.

  2. I/O Modules: These modules establish connections between the controllers and field devices, such as sensors and actuators.

  3. Communication Network: The communication network links controllers, I/O modules, and other system components, enabling seamless data exchange.

  4. Operator Workstations: Operator workstations provide a means for operators to monitor and control the industrial processes.

The TDC 2000 is known for its exceptional reliability and robustness. It has successfully operated in the field for over four decades and continues to be used in various applications. However, it's important to note that the TDC 2000 is considered a legacy system and is no longer supported by Honeywell.

Honeywell has introduced more advanced DCS systems, such as the TDC 3000 and the Experion PKS, which offer enhanced features and functionality compared to the TDC 2000 and are actively supported by Honeywell.
